Perhaps the first point to address in this chapter is what role, or roles, experimental petrology
can play in understanding the formation of natural diamond. As can be seen from the other …

Earth carbon cycle shapes the evolution of our planet and our habitats. As a key region of
carbon cycle, subduction zone acts as a sole channel transporting supracrustal carbonate …

The reactions between pyroxenes and carbonates have been studied in the CaMgSi 2 O 6+
MgCO 3 (Di+ 2Mgs), CaMgSi 2 O 6+ NaAlSi 2 O 6+ 2MgCO 3 (Di+ Jd+ 2Mgs), CaMgSi 2 O …

Fe3O4 is a common earth mineral, which often exists in the form of inclusions in natural
diamond. It is important to explore the effects of various proportions of Fe3O4 dopants on the …

Mg-carbonate is one of the main carbonates subducting from the Earth's surface into the
mantle and possible reactions of this compound with the main mantle minerals determine …

We synthesized an iron carbonate, Fe23+ [CO3] 3, by reacting Fe2O3 with CO2 at high
temperatures and pressures of approximately 33 (3) GPa. The structure was solved by …

A large set of nucleobases and amino acids is found in meteorites, implying that several
chemical reservoirs are present in the solar system. The “geochemical continuity” hypothesis …

It is generally accepted that carbonates can be subducted to the mantle depths, where they
are reduced with iron metal to produce a diamond. In this work, we found that this is not …

Sedimentary carbonates are known to be carried into the deep mantle by subducted slabs,
and studies on mantle‐derived magmas have attempted to trace the recycled carbonate in …

Due to the significantly reduced conditions in the mantle below~ 250 km, carbonates
transported by the subducting oceanic plates will inevitably interact with Fe-saturated mantle …
